The condition that is deliberately changed using the scientific method in a controlled experiment is the independent variable. It can also be called the manipulated variable.
It is the mass defect during a fission reaction. Enrgy evolved during a radioactive fission can be calculated using the formula gived by Einstein e =mc
Energy coupling
Catalysis is the action to increase the reaction rate of a chemical reaction using substances called catalysts which are not transformed during this reaction.
The rate of a reaction is calculated using the concentrations of reactants.
It all depends on what chemicals you are using. For example, if you were using sulfur & carbon, either one could be changed.
to stop using polythene's
we can control the use of plastics by using paper bags instead of polythene bags, by recycling some plastics and using renewable resources.
A reaction that can be described using a word

It is made by a process called polymerization, this is where they take lots of monomers (in this case ethene) and combine them together using an addition reaction. This is only possible in monomer where there is a double bond as to add them the double bond has to break for there to be enough room on the carbon for the new monomer. This process is done millions of times and is finally makes polythene which is used to make bin liners and poly bags. This is the proses: Crude Oil -> Crude Oil Vapour --> Diesel Oil --> Ethene --> Polythene
You're probably having a reaction to something in the new face wash that you are using. Rinse your face with clean, warm water and then stop using that certain face wash.
Disadvantage is that polythene once made cant be destroyed ever............polythene is big terror to our environment also Polythene is not biodegradable, and if dumped in the soil causes harm to the plant life, as the toxic substances of polythene get blocked among the soil particles. . Polythene threatens the life in the water bodies. The chemicals in polythene affects the survival of flora and fauna of the aquatic and marine eco systems. . Polythene is also likele to clog the drains causing problems in the water flow of the pipes. The pipe blockages would cause flooding and the free flow of water is disturbed. . Polythene is harmful for animals if swallowed. It solidifies inside the abdominal cavitywhich ultimately becomes lethal to the animal. . In most households poly bags are used to preserve food items. It has been found out, the colourful poly bags contains lead and cadmium which are toxic and causeadverse effects to human health. . If polythene is burnt in open air Hydrogen cyanide which is carcinogenic (cancer causing) is released. Hydrogen cyanide causes environmental pollution and health hazards
